and that its cable is properly connected to the DC IN 12V connector 

on the transmitter. 

Ensure that the headphones On/Off switch is switched to the On.

Start playback on by the equipment. 

Check the battery compartments if batteries are at right positions.

Use the channel selector to change the transmitter's transmission 

frequency. Then you will need to adjust the tuning control on the 

headphones until the "Stereo" indicator comes on. 

The headphones battery charge level may be too low. Recharge the 

batteries or replace them with fully charged batteries. 

Ensure that the volume knob setting is correct. 

The headphones may be too far away from the transmitter. Move 

closer to it. 

The audio signal input level is too low. Increase the volume from the audio
